Presently competing on the new season of Dancing With The Stars, McKellar is well-known for her starring roles on the television series The Wonder Years and The West Wing and for her candid, bestselling books that motivate girls in mathematics: Math Doesn’t Suck, Kiss My Math, Hot X: Algebra Exposed, and Girls Get Curves: Geometry Takes Shape. Joining McKellar at the festival will be acclaimed Flatland filmmakers Seth Caplan and Dano Johnson.

“Movies and television play an important role in shaping the narrative for kids around STEM,” said Dr. Ray O. Johnson, Festival co-founder and Lockheed Martin senior vice president and chief technology officer. “Danica has been a tremendous education advocate not only on screen, but also through her STEM-focused books to help make math more accessible and relevant to girls.”

McKellar will be featured on the Lockheed Martin stage among a rotation of inventors, entrepreneurs and celebrities April 26-27, 2014 at the Walter E. Washington Convention Center in Washington, D.C.

In addition to the stage, Lockheed Martin engineers and technologists will showcase awe-inspiring technologies and interactive, hands-on exhibits in the areas of advanced aeronautics, data analytics, scientific discovery, nanotechnologies, robotics and energy.
